What is a coefficient in algebra?

Back

A coefficient is a numerical factor that multiplies a variable in an algebraic expression. For example, in 3x, 3 is the coefficient.

What are terms in an algebraic expression?

Back

Terms are the individual components of an expression separated by plus or minus signs. For example, in the expression 2x + 3y - 5, the terms are 2x, 3y, and -5.

What does it mean to combine like terms?

Back

Combining like terms involves adding or subtracting terms that have the same variable raised to the same power. For example, 2x + 3x = 5x.

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to multiply a single term by each term inside a parenthesis.

How do you apply the distributive property to simplify expressions?

Back

To apply the distributive property, multiply the term outside the parentheses by each term inside the parentheses. For example, 2(x + 3) becomes 2x + 6.

What is the difference between an expression and an equation?

Back

An expression is a combination of terms without an equality sign, while an equation states that two expressions are equal, using an equality sign.

Front

What does it mean to simplify an expression?

Back

Simplifying an expression means to reduce it to its simplest form by combining like terms and applying the distributive property.
